Last weekend, our team at work decided to go out for dim sum. One thing I have learned about ordering dim sum from some of my co-workers is that...

Kingston SSDNow UV400 480GB Review (Page 4 of 11)

Page 4 - Benchmark: ATTO Disk Benchmark

About ATTO Disk Benchmark

The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.

Following up next is our usual ATTO read and write tests. ATTO is an often quoted benchmark, because it is easy to use and accurate. For the most part, it is a favorite among reviewers, and I have grown to embrace it as much as the next for the last little while. ATTO uses easily compressible data, so SandForce based SSDs and similar will perform very well here; as far as the Marvell 88SS1074 is concerned -- well, here are our results. As manufacturer peak read and write performance ratings are usually obtained using ATTO, whether a drive lives up to its marketing claims or not can be validated by this program. Kingston claims the SSDNow UV400 480GB's maximum read and maximum write are pinned at 550MB/s and 500MB/s, respectively. According to our tests, these numbers were slightly underrated. It peaked at 561.841MB/s read and 530.242MB/s write. Under the curve, it was somewhat between the Crucial MX300 and OCZ Trion 150. Its read curve was consistently slower than the OCZ Trion 150 by quite wide a margin, but had a considerable lead over the MX300. As far as write is concerned, the UV400 kept the Trion 150 under the entire envelope with a curve similar to the MX300, although the MX300 maintained a slight edge in performance.
